BEDSTEAD.

Specification of Letters Patent.

Patented Dec. 22, 1908.

Application filed June 23, 1908. Serial No. 439,937.

To all whom it may concern:

Be it known that I, HARRY B. ARNOLD, a citizen of the United States, residing at New Britain, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Bedsteads, of which the following is a specification.

My invention relates to improvements in iron bedsteads and the main objects of my improvement are sim licity and economy in construction, while t e article is rigid and substantial.

In the accompanying drawing :Figure 1 is a broken out plan view of my bed bottom together with a sectional view of two legs of one of the end frames which complete the bedstead. Fig. 2 is a broken out side eleva tion of one of the end frames for my bedstead. Fig. 3 is an end view of one corner of my bed bottom. Fig. 4 is a front view of the same. Fig. 5 is a view of one corner iron and attached end rail of my bed bottom as viewed from the opposite direction from that shown in Fig. 3, the side rail of the bed bottom being removed from the said corner iron.' Fig. 6 is a transverse section of one of the end rails of my bed bottom, together with a side elevation of one corner iron. Fig. 7 is a broken front elevation of one corner of my bedstead com lete. Fig. 8 is a horizontal section on the ins 00 m of Fig. 7, of one corner iron and one post or leg of one of the end frames, together with a plan view of one of the bolts by which they are fastened together, and a sectional view of the thumb nut belonging to the said bolt.

My bedstead is composed of a bed bottom with corner irons, and four legs secured directly to the corner irons of the bed bottom, which legs as shown, are formed on the end frames of the bedstead.

The bed bottom is composed of four corner irons A, B; A, B; two end rails C, two side rails D, and a mattress support stretched between the said end rails. I prefer to form all these parts of iron and steel, and to form the mattress support of a reticulated wire fabric 9, that is connected with the end rails by means of springs 10, all substantially as in the bed bottoms known as the National Y spring bed. Part of the metal fabric and its I springs are omitted from Fig. 1.

socket 11, to receive the ends of the side rails, and with top flanges 12 that extend u wardly from the outer ends of the said socl ets, to the upper ends of which flanges the respective ends of the angle iron end rails C are secured by rivets 13. After the corner irons are thus secured to the end rails in pairs, the side bars D are inserted in the res ective sockets 11 of the corner irons and t e fabric is stretched on the said end rails to hold the parts in place and form a complete bed bottom that is entirely separate from any bedstead, as shown for the left hand end of the bed bottom in Fig. 1. Such a bed bottom can be placed on any suitable bedstead or support in any ordinary manner.

In order to form such a separate bed bottom so that it can be readily converted into a bedstead by the attachment of four legs or two end frames having legs, I form corner irons A, B, with a vertical flange 14 that projects outwardly from the inner side at one end of each corner iron and has a curved form in plan view so as to substantially fit a portion of the side of a tubular post or leg that forms a part of one of the end frames of the bedstead. In order to save fitting I form transverse ribs 15, at the upper and lower ends of the flanges 14, which ribs have the desired curve in plan view to fit the said parts and merge into the said flange so that the said flange and ribs together form a horizontally curved and vertically extended leg receiving socket on each corner iron at the outer ends of the bedbottom. These leg receiving sockets open diagonally outwards from the inner corner of each angle iron. In connection with the said flange I form a boss 16 on the back or inner faces of the flanges 14 and form a bolt hole 17 horizontally through the said boss and flange, which hole extends obliquely through the corner of each corner iron as best shown in Fig. 8. This is all the change that is necessary to make in the corner irons from those of an ordinary bed bottom. A bed bottom with these corner irons can be used on an ordinary bedstead or other support.

I'form the end frames, Fig. 2, with corner posts or legs 18, one leg for each corner iron. As shown, I form these legs of tubes or piping and extend them upwardly farther than is necessary to serve as a mere leg and connect the said upper ends by means of cross rods 19, and I may add ornamental knobs 20 to the upper ends of the posts and other ornaments as desired to form suitable end frames for the two ends of the bedstead. The lower part of the posts 18 constitute the tubular legs of the bedstead and all that is necessary to fit the legs to the corner irons to convert the bed bottom into a bedstead, is to form holes 21, Fig. 2, through the posts or legs at the proper oblique angle. These posts or legs are applied to the vertically extended sockets at the ends of the bed bottom and then secured firmly thereto by suitable means for fastening, as for example by means of bolts 22, which are extended through the holes in the legs and corner irons and are secured within the said holes by the thumb nuts 23. It is best to employT bolts having curved heads 24 that embrace a considerable portion of the circumference or one side of the hollow or tubular posts, so as not to crush and flatten them. The strain of the fabric on the end rails has a tendency to cock or tilt the corner irons slightly and consequently Imake the concave face of the open vertical socket, at a slightly obtuse angle to the length of the horizontal sockets 11, as shown in Fig. 7, so that the posts or legs will stand straight up when the corner irons are slightly tilted.

In practice I intend to set up the bed bottoms complete in the factory and to form the end frames or legs with simple holes for attachment to the bed bottom and to ship them in connection with the proper bolts and nuts with the end frames unattached. The construction is so simple that the receiver can readily set them up, and thumb nuts are used so that he may put the bedstead together without the employment of a wrench. The construction is not only simple and inexing sockets, the faces of which latter sockets extend vertically at an obtuse angle to the length of the first named sockets.

2-. In a bed bottom having side and end rails, corner irons for connecting the said rails, the said corner irons having at their lower part horizontally extended side rail receiving sockets, and at the outer ends of the said sockets and inner corner of the said corner irons, laterally curved and vertically extended flanges forming leg receiving sockets that open diagonally outwards from the said inner corners.

3. In a bed bottom having side and end rails, corner irons for connecting the said rails, the said corner irons having at their lower part horizontally extended side rail receiving sockets, and at the outer ends of the said sockets and inner corner of the said cor ner irons, laterally curved and vertically extended flanges forming leg receiving sockets that open diagonally outwards from the said inner corners, the said flanges having on their reverse sides bolt hole bosses and bolt holes extending through said bosses and flanges.
